Heh. On the album version of this song, the lyrics for the first chorus are:

Inside down and upside out
and you can feel it.
Don’t stop.
Can’t stop.It’s like an airplane goin’ down.
I wish I had said the things you thought that I had said.
Gravity’s just a habit that you’re really sure you can’t break.

Emphasis mine. For this video version, “It’s like an airplane goin’ down” becomes “Until you can feel it goin’ down.” And there’s another instance of “an airplane goin’ down” that was changed.
